Statistical agencies are interested in publishing useful statistical data but doing so may lead to the disclosure of individuals’ pri¬vate data. This is a problem, as it leads to a trade-off between the utility of the published data and the risk of disclosure of confiden¬tial data. Disclosure control can be seen as the use of methods to deal with this problem by assessing and controlling the risk of dis¬closing confidential data while also providing researchers with useful statistical data. This talk describes a disclosure control model based largely on Bayesian decision theory. This model allows for the description of the concepts of disclosure control in terms of familiar statistical con¬cepts such as expectation and variance. A method of disclosure con¬trol, called Random Tabular Adjustment (RTA), is described. This method controls the risk of disclosure by randomly adjusting the data instead of suppressing cells. It fits naturally into the disclosure control model described.
